EBS vs EFS - Block Storage vs File Storage on AWS - Platform Engineering Hands-On Lab Icon

Lab Overview

Hands-on comparison of Amazon EBS and Amazon EFS. You will create a VPC with two public subnets, launch instances in different Availability Zones, attach a gp3 EBS volume, and create an EFS file system shared across both instances.

You'll learn to:

  • Create and attach a gp3 EBS volume, then format and mount it
  • Create an EFS file system with mount targets in two AZs
  • Mount EFS on multiple instances and verify shared access
  • Compare access patterns: single-attach/single-AZ (EBS) vs multi-attach/multi-AZ (EFS)
  • Decide when to pick EBS vs EFS based on workload requirements
